UGVER-LOCK.

Application filed September 15, 19(78.

Specification of Letters Patent.

Patented April 13, 1909.

Serial No. 453,122.

T 0 all whom it may concern:

Be it known that I, WILLIAM C. Monninn, a citizen of the United States,and a resident of New York city, in the county of New York and State ofNew York, have invented certain new and useful Improvements inCover-Locks, of which the following is a specification.

The invention relates to a lock adapted to be connected with a hin ed orremovable lid or cover of a receptacle, of which a full, clear, andexact description will be given hereinafter.

The invention consists of a combination of a receptacle having one ormore depressions or perforations made on a portion of its exteriorsurface near its mouth or end, and a lid or cover provided wit-hmechanical con trivances adapted to engage with the depressionsaforesaid, thereby forming a lock, all of which will be fully describedand pointed out in the claims hereinafter.

In the drawings, Figure 1 is a plan of the removable lid or cover. Fig.2 is a front elevation of the lid or cover mounted upon the receptacle.In this view is shown the cap covering the lock, and the keyholetherein. Fig. 3 is a vertical section of Fig. 1 taken on the line :0. w.and also shows the operative part of the key inserted in the lock. Fig.i is a view with the cap covering the lock removed, showing the keyseat. In this view a part only of the lid or cover is shown. Fig. 5represents a portion of the receptacle in which is shown one of thedepressions and the form adapted in this par ticular case. Fig. 6 is aportion of the cover showing the cap with key hole covering the lock.Fig. 7 is a vertical section taken through the cap covering the lock,and shows the rotatable bolt mounted upon the rim. Fig. 8 is a side viewof the rotatable bolt and key seat only.

Similar letters refer to similar parts throughout the drawings, in whichis shown the receptacle a provided with the depressions b and 6. Thesedepressions b and b consist of grooves open at the top and terminatingin enlarged recesses. The recesses are preferably made circular in shapeal though any form may be used. The enlarged portions of the aforesaiddepressions are adapted to receive the projection c which may beintegral or otherwise connected with the depending annular rim (Z of thelid 6. The projection c is made so as to enter and almost fill up therecess and is also made so large that it cannot enter the groove whichopens into the aforesaid recess. The larged portions of the depressionsZ) and Z) are also adapted to receive the rotatable bolt 7, the latterof which is mounted upon the inner end of the rotatable stem g and at.right angles to it. The other end of the rotatable stem 9 is fixedlysecured to a rotatable key seat disk /L. The bolt f is rec tangular insection, the smaller side being a little smaller in size than the widthof the groove, and the larger side a little larger than the width of thegroove, and a little smaller than the diameter of the circular recess.The rotatable bolt f and its key seat /t are mounted closely togetherupon opposite sides of the rim (5 so that the curvature of the rim actsas a spring and keeps the lock in any desired fixed position. Over thekey seat disk It is placed the cap or nipple 2', rovided with a keyhole.

Mode of operation: When the receptacle, which in this case is made ofglass and is used as a holder for liquid soap, shall have been filled,the lid 6 will be first placed so that the projection c is within thecircular recess of either the depressions 7) or Z). The rotatable bolt7' will then be turned so that its long side lies lengthwise of thegroove of the other depression. Then as the lid c is swung downward uponthe receptacle from the projection c as a fulcrum, the bolt 7" willenter and travel through the upper groove of the depression into thecircular recess. The inner diameter of the lid is made a little largerthan the outer diameter of the receptacle so as to permit thisoperation. llhen the cover (2 has come to rest the bolt 7 is turned atright angles to its direc tion of entrance within the circular recess bymeans of the key is, which enters the cap i by means of the key hole andoperates the key seat ]L. Then the key is removed and the lid 0 willhave become locked to the receptacle.

As both the projection c and the bolt 7 are made so deep as not to besprung sidewise over the side of the receptacle, and both the projectionand the longer side of the bolt are made so as to lie across theenlarged circular recess and are larger than the width of the grooves ofthe depressions, it is obvious that he cover 6 cannot be removed exceptby insertin the key and turning the bolt so that it will lie lengthwiseof the groove and travel up through it, as the cover 6 is swung upwardon the projection c as a fulcrum;

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

1. In a lock for receptacles, the combination, consisting of areceptacle provided with a groove open at the top and terminating in anenlarged recess, and a cover provided with a rotatable bolt adapted toenter through the aforesaid groove into the aforesaid recess and form alock therewith.

2. In a lock for receptacles, the combnnn tion, consisting of areceptacle provided with depressions, a lid provided with a projectionadapted to engage with one of the aforesaid depressions, and a boltconnected to the lid and adapted to lock with a second depression.
